What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimMonochorionic twins are at higher risk of perinatal mortality and morbidity, primarily due to pregnancy-related complications, such as twin-to-twin transfusion syndrome (TTTS). We aimed to investigate whether amplitude-integrated electroencephalography (aEEG) signals are different between monochorionic twins with and without TTTS.
methodsThis was a retrospective single-centre study conducted at Innsbruck Medical University Hospital, Austria. Preterm infants born before 32 weeks of gestation between 6 November 2010 and 6 December 2022 were eligible. The aEEG was analysed for the total maturation score, its component scores and the number of sleep-wake cycles per hour.
resultsWe enrolled 79 monochorionic twin infants (48% male) and 157 dichorionic (62% male) twin infants. We found no differences between these two groups of preterm infants regarding the total maturation and component scores, or the number of sleep wake cycles. Monochorionic twins with TTTS showed significantly lower total maturation scores and individual component scores compared to monochorionic twins without TTTS.
conclusionPreterm infants with TTTS showed differences in neonatal aEEG signals. Whether these differences are caused by prematurity-related or TTTS-related factors, such as hemodynamic and metabolic changes due to placental anastomoses, should be investigated in future prospective studies, to gain more insight into this important topic.
